Definitions
- the present invention relates to a wear-resistant lining for one Building material mixer according to the preamble of claim 1.
- Wear-resistant linings for building material trough mixers have long been known (compare DE-B-12 37 936 and DD-A-41 453) and have largely changed proven.
- comparable wear-resistant linings are also in Connection with ball mills known (see GB-A-1 401 580).
- a first food for thought about a new, screwless one Wear plate mounting for building material trough mixers can be found in DD-A-41 453.
- the wear plates are placed on the inner wall of the trough and braced against each other in the manner of a support arch.
- the axes are parallel Wear plate edges butt against each other and it is obvious that there is a risk that this over these axially parallel abutting edges if there is any unevenness, the mixed material is pushed away under the wear plates Circumstances takes off.
- the object underlying the present invention is a to indicate wear-resistant building material trough mixer linings of the generic type, which is initially to be fastened without screw holes and which in particular Direction of movement of the mixed material is well “interlocked” with one another so that the wear plates are still “interlocked” well when they are are removed over half of the initial thickness.
- the At the heart of the present invention is the lining of a building material trough mixer simply put on, holding each other via a complementary latching to realize supporting wear plates that connect seamlessly to each other, and the across, i.e. along the axially parallel edges, are interlaced relative to each other.
- a training or special design of the wear-resistant Lining is the subject of claim 2.
- the mixing trough 1 is a cylindrical body, the inner wall 2 with Wear plates 3 is occupied. These wear plates 3 are the curvature of the Inner wall 2 bent accordingly, so that they lie flat against this. Basically, it does not matter whether the wear plates 3, as in the drawing shown, arranged like a checkerboard or whether, for example, with a given Pitch are offset from each other in the circumferential direction.
- the present invention relates to attachment the wear plates 3 in the mixing trough 1. It must be assumed that the Wear plates 3 each on their axis parallel to the axis of the mixing trough 1 edges in pairs convex-concave complementary wedge-shaped tongue and groove-like Have shapes 4+, 4-.
- the wear plates 3 are so - in Considered circumferential direction - attached to each other, so that they are quasi self-supporting on the Fit and rest on the inner wall 2 of the mixing trough 1.
- each parallel to the edges of the filling opening 5 of the mixing trough 1 a clamping bar 6, 7 is provided, the edge formations of which are convex-concave Groove / tongue-like shapes 4+, 4- correspond to the wear plates 3.
- the wear plate 3 is thus viewed in the axial direction of the mixing trough 1 alternating convex edges 4+ or concave edges 4- are provided so that two wear plates 3 are quasi entangled with each other.
- Fig. 2b shows a view along the section line I-I and that across the three adjacent wear plates 3. This illustration also applies to section line III-III.
- Fig. 2c shows a view along the section line II-II, i.e. through the middle of the three adjacent wear plates 3.
- wear plates 3 have been removed up to the middle, they remain still over the alternating slopes 42 and 44 relative to each other "interlocked" with each other.

Description
- Fig. 1
- die Prinzipdarstellung einer verschleißfesten Auskleidung anhand eines aufgeschnittenen Mischtrogs für einen sogenannten Einwellen-Trogmischer, wobei die Verschleißplatten kantenseitig nut- / feder-ähnlich alternierend verschränkt "verzahnt" sind;
- Fig. 2
- eine Detaildarstellung entsprechend der Ansicht "A" nach Fig. 1 mit je einer Schnittdarstellung quer zur Mischerlängsachse und zwar längs der Schnittlinien I-I, II-II und III-III durch je drei in Umfangsrichtung benachbarte Verschleißplatten nach Fig. 1.
- entsprechend den Schnittlinien I-I, II-II und III-III die aneinander anliegenden Verschleißplatten 3 jeweils drei komplementäre Kantenausbildungen haben, die
- entsprechend der - bezogen auf die Breite der Verschleißplatten 3 - mittigen Schnittlinie II-II, insoweit invertiert ist, als die konvexen Kanten 4+ in eine konkave Kante 4- übergehen und umgekehrt.
- die konvexe Kantenausbildung 4+ über einen geraden Absatz 41 und eine hinterschnittene Schräge 42 und
- die konkave Kantenausbildung 4- über einen geraden Absatz 43 und eine
vorstehende Schräge 44
entsteht. Die geraden Absätze 41 / 43 reichen dabei jeweils vorzugsweise von der Innenseite der Verschleißplatten 3 bis etwa zur halben Plattenstärke.
Claims (2)
- Verschleißfeste Auskleidung für einen Baustoff-Trogmischer,
bestehend aus einer Vielzahl dicht nebeneinander angeordneter auswechselbarer Verschleißplatten, dieeinerseits auf der Innenwand (2) des Mischtrogs (1) aufliegend nach Art eines Stützbogens verspannt sind, undandererseits längs ihrer achsparallel zum Trogmischer liegenden Kanten konvex-konkave komplementäre Formgestaltungen aufweisen,
dadurch gekennzeichnet,daß jede Verschleißplatte (3) längs ihrer achsparallel zum Trogmischer (1) liegenden Kanten jeweils mindestens zwei gegensinnig orientierte Formgestaltungen (4+, 4-; 41, 42, 43, 44) aufweist,so daß je Kante mindestens eine konvexe und eine konkave Form realisiert sind. - Verschleißfeste Auskleidung für einen Baustoff-Trogmischer nach Anspruch 1,
dadurch gekennzeichnet,daß die konvex/konkave Formgestaltung durch jeweils eine hinterschnittene Schräge (42) bzw. eine vorstehende Schräge (44) gebildet sind, die von der an der Innenwand (2) anliegenden Seite der Verschleißplatten (3) her insbesondere bis etwa zur Mitte der Verschleißplattendicke reichen.
